BACKGROUND

Technical Field

The disclosure relates to a touch device, and in particular it relates to the design of the conducting lines of the touch device.

Description of the Related Art

Conventional touch devices usually include a touch-sensing region, a bonding pad set, and a plurality of conducting lines on a substrate. The conducting lines may electrically connect the bonding pad set with a plurality of sensing electrodes in the touch-sensing region, and a plurality of bonding pads of the bonding pad set are usually electrically connected to an external circuit (e.g. a flexible circuit board), such that current or signals can be transferred from the external circuit to the touch-sensing region through the bonding pads and the conducting lines. As such, the touch device can be driven by the current or the signals.

In a conventional design, the conducting lines surrounding the touch-sensing region have a same width in all regions, and the adjacent conducting lines have a fixed space. On the other hand, general terminals of the conducting lines electrically connected to the sensing electrodes are rectangular-shaped. The above design easily accumulates a large amount of static charges, thereby negatively influencing the performance of the touch device by electrostatic discharge (ESD), and even damaging the touch device.

Accordingly, a novel design for conducting lines to prevent the conventional ESD problem is called-for.

DETAILED DESCRIPTION

The following description is of the best-contemplated mode of carrying out the disclosure. This description is made for the purpose of illustrating the general principles of the disclosure and should not be taken in a limiting sense. The scope of the disclosure is determined by reference to the appended claims.

As shown in FIG. 1, a touch-sensing electrode layer on a substrate 10 of a touch device 100 includes a touch-sensing region 13 and a non-touch-sensing region 14 located outside of the touch-sensing region 13. In other embodiments, the non-touch-sensing region 14 may be located surrounding the touch-sensing region 13 or adjacent to the touch-sensing region 13. The touch-sensing region 13 includes at least one sensing electrode 131. Conducting lines 11 on the substrate 10 are located in the non-touch-sensing region 14, and are electrically connected to the sensing electrodes 131 in the touch-sensing region 13. Another terminal of the conducting lines 11 is electrically connected to bonding pads 15, and the bonding pads 15 can be further electrically connected to an external circuit such as a flexible circuit board (not shown). Current or signals of the external circuit can be transferred to the touch-sensing region 13 through the bonding pads 15 and the conducting lines 11 to drive the touch device 10, and signals produced by a user touching the touch-sensing region 13 can be also transferred to the external circuit through the conducting lines 11 and the bonding pads 15. In one embodiment, the substrate 10 can be glass or polymer film. In one embodiment, the conducting lines 11 can be aluminum, molybdenum, copper, silver, an alloy thereof, or a multi-layered structure thereof. The bonding pads 15 can be the same material of the conducting lines 11, or another electrically conducting material such as indium tin oxide (ITO) or indium zinc oxide (IZO). As shown in FIG. 1, terminals 11′ of the conducting lines 11 electrically connecting to the sensing electrodes 131 are arc-shaped rather than rectangular-shaped, thereby preventing the accumulation of charges on the terminals 11′. It should be understood that the conducting lines 11 in FIG. 1 are only for illustration, and their real size, width, or spacing can be verified as shown in following embodiments.

FIG. 2A shows an enlarged diagram of the corner region 20 in FIG. 1 of one embodiment. In FIG. 2A, the non-touch-sensing region 14 is divided to non-curve regions 14A and 14C and a curve region 14B, wherein the curve region 14B connects the two non-curve regions 14A and 14C. It is illustrated by the case of the outermost conducting line 11, which has a width W1 in the non-curve region 14A, a width W2 in the curve region 14B, and a width W3 in the non-curve region 14C. As shown in the FIG. 2A, the width W2 of the conducting line 11 in the curve region 14B is greater than the widths W1 and W3 of the conducting line 11 in the non-curve regions 14A and 14C. The width of the conducting line in the curve region is greater than the width of the conducting line in the non-curve region in the disclosure, thereby reducing the charge density per area unit of the conducting line in the curve region. As such, the charges do not easily accumulate in the curve region, and the ESD problem can be mitigated. It should be understood that the conducting lines 11 in the non-curve region 11A extend toward a direction 21A, the conducting lines 11 in the non-curve region 14C extend toward a direction 21C, and the conducting lines 11 in the curve region 14B extend toward a direction 21B. As shown in FIG. 2A, the direction 21A is different from the direction 21C, and the direction 21B is different from the directions 21A and 21C. The directions 21A and the 21C have an angle α therebetween, and the angle α is greater than 0° and less than 180°. Although the direction 21A is vertical to the direction 21C in FIG. 2A, the directions 21A and 21C may have another direction determined by the shape of the substrate 10 in FIG. 1. For example, if the substrate 10 is triangle, hexagon, octagon, or another polygon, the directions 21A and 21C will have other corresponding angles rather than being vertical to each other. Whatever the angle α between the directions 21A and 21C being, the direction 21B will gradually change from the direction 21C to the direction 21A. The conducting lines 11 in the curve region 14B have a tangent direction 21B′, the direction 21C and the tangent direction 21B′ have an angle β, and the angle β is greater than 0° and less than the angle α.

In one embodiment, the width W1 of the conducting lines 11 in the non-curve region 14A is similar to the width W3 of the conducting lines 11 in the non-curve region 14C. Moreover, the width of the inner conducting lines 11 is similar to the width of the outer conducting lines 11. In another embodiment, the outer conducting lines 11 (far away from the touch-sensing region) have a wider width, e.g. larger widths W1, W2, and W3. In other words, the inner conducting lines (closer to the touch-sensing region) have a narrower width, e.g. smaller widths W1, W2, and W3, as shown in FIG. 2B.

In one embodiment, the width W1 of the conducting lines 11 in the non-curve region 14A is greater than the width W3 of the conducting lines 11 in the non-curve region 14C, as shown in FIG. 2C. As such, the width W2′ of the conducting lines 11 in the curve region 14B adjacent to the non-curve region 14A is greater than the width W2″ of the conducting lines 11 in the curve region 14B adjacent to the non-curve region 14C. In one embodiment, the concept of FIG. 2B (the outer conducting lines have a greater width) and the concept in FIG. 2C (the widths of the conducting lines in different non-curve regions are different) can be combined, as shown in FIG. 2D.

FIG. 3A shows an enlarged diagram of the corner region 20 in FIG. 1 of one embodiment. In FIG. 3A, the non-touch-sensing region 14 is divided to non-curve regions 14A and 14C and a curve region 14B, wherein the curve region 14B connects the two non-curve regions 14A and 14C. It is illustrated by the case of the two outermost conducting lines 11 (e.g. the first conducting line 11A and the second conducting line 11B), which have a space D1 therebetween in the non-curve region 14A, a space D2 therebetween in the curve region 14B, and a space D3 therebetween in the non-curve region 14C. As shown in the FIG. 3A, the space D2 between the two adjacent conducting lines 11 (e.g. the first conducting line 11A and the second conducting line 11B) in the curve region 14B is greater than the spaces D1 and D3 between the two adjacent conducting lines 11 (e.g. the first conducting line 11A and the second conducting line 11B) in the non-curve regions 14A and 14C. The space between the two adjacent conducting lines (e.g. the first conducting line 11A and the second conducting line 11B) in the curve region is greater than the space between the two adjacent conducting lines (e.g. the first conducting line 11A and the second conducting line 11B) in the non-curve region in the disclosure, thereby reducing the coupling problem of the two adjacent conducting lines (e.g. the first conducting line 11A and the second conducting line 11B) in the curve region. As such, the ESD problem can be prevented. Definitions of the extending directions of the conducting lines 11 in the non-curve regions 14A and 14C and the curve region 14B, the tangent direction of the conducting lines 11 in the curve region 14B, the angle between the extending directions of the conducting lines 11 in the non-curve regions 14A and 14C, and the angle between the extending direction of the conducting lines 11 in the non-curve region 14A and the tangent direction of the conducting lines 11 in the curve region 14B are similar to that in FIG. 2A and the related description was therefore omitted here.

In one embodiment, the space D1 between the two adjacent conducting lines (e.g. the first conducting line 11A and the second conducting line 11B) in the non-curve region 14A is similar to the space D3 between the two adjacent conducting lines (e.g. the first conducting line 11A and the second conducting line 11B) in the non-curve region 14C, and the space between the two adjacent inner conducting lines 11 (e.g. the third conducting line 11C and the fourth conducting line 11D) are similar to the space between the two adjacent outer conducting lines 11 (e.g. the first conducting line 11A and the second conducting line 11B). In another embodiment, the two adjacent outer conducting lines 11 (away from the touch-sensing region, e.g. the first conducting line 11A and the second conducting line 11B) have a wider space therebetween, e.g. larger spaces D1, D2, and D3. In other words, the two adjacent inner conducting lines 11 (closer to the touch-sensing region, e.g. the third conducting line 11C and the fourth conducting line 11D) have a narrower space therebetween, e.g. smaller spaces D1, D2, and D3, as shown in FIG. 3B.

In one embodiment, the space D1 between the two adjacent conducting lines 11 in the non-curve region 14A is greater than the space D3 between the conducting lines 11 in the non-curve region 14C, as shown in FIG. 3C. As such, the space D2′ between the two adjacent conducting lines 11 in the curve region 14B adjacent to the non-curve region 14A is greater than the space D2″ between the two adjacent conducting lines 11 in the curve region 14B adjacent to the non-curve region 14C. In one embodiment, the concept of FIG. 3B (the outer adjacent conducting lines, e.g. the first conducting line 11A and the second conducting line 11B, have a greater space therebetween) and the concept in FIG. 3C (the spaces of the adjacent conducting lines in different non-curve regions are different) can be combined, as shown in FIG. 3D.

In addition, the concept in FIGS. 2A-2D (the conducting lines in the curve region have a greater width) and the concept in FIGS. 3A-3D (the two adjacent conducting lines in the curve region have a greater space therebetween) can be combined. In one embodiment, a conducting line having a greater width will have a greater space with the conducting line adjacent to it.
